Nvidia shows Vera Rubin NVL72 running OpenAI workloads in new lab

Nvidia gave Tom's Hardware an exclusive look at its previously undisclosed Engineering SuperLab, where Vera Rubin NVL72 racks are running live OpenAI workloads. The visit also demonstrated 800V DC power delivery for the rack-scale systems.

Why it matters: This is Nvidia showing its next-generation rack-scale platform already handling production-grade workloads from a top customer, not just lab benchmarks, a concrete signal that Vera Rubin's ramp is ahead of the usual hype-to-shipping gap. The 800VDC demo also points to the power-delivery redesign needed as AI data centers push past what standard AC infrastructure can efficiently support.
